Barracuda Backup requires an Energize Updates subscription for firmware upgrades and Technical Support. Energize Updates are also required to maintain compatibility with the Barracuda Backup Cloud (accessed through login.barracuda.com). Barracuda Backup performs updates to the cloud to maintain compatibility with the latest legacy, general, or early release firmware versions. Barracuda Backup devices with expired Energize Updates running unsupported firmware versions may experience difficulties using the Barracuda Backup Cloud for management as well as services such as data replication.
This does not apply to the local web-based management interface which is accessible for restores or the Local Control management option.
If your Energize Updates Subscription expires, contact Barracuda Sales to renew your subscriptions.
Automatic Firmware Upgrades
Barracuda Backup enables administrators to perform manual upgrades at a time that is convenient, however, Barracuda performs automatic upgrades for Barracuda Backup devices with an active Energize Update subscription if they are running unsupported firmware versions.
After a major firmware version has completed the rollout phase, Barracuda sends an upgrade notification, providing 30-day's notice before the upgrade takes place. This notification includes information on new features, bug fixes, and end-of-life announcements. You must subscribe to email notices to receive the upgrade notifications.
